In lieu of an abstract, here is a brief excerpt of the content:Soldiers of the Invisible Front: How Ukrainian Therapists Are Fighting for the Mental Health of the Nation Under FireIrina Deyneka and Eva RegelIrina DeynekaWhen the Russian army attacked my country, I became a volunteer for a hotline offering psychological support to those in crisis; refugees, those who were under the shelling, those who were hiding in bomb shelters, and who were directly in the zone of fighting. People (...) were lost and disoriented by constant bombing, by the fact that their country was under attack. Once, I had a woman who lived in Mariupol on one of these calls. I was living then in another city, Odessa, but was experiencing the same horrors of war that my client was—the shelling, uncertainty, and despair. We were processing my client’s feelings of grief and anxiety when I heard the sirens on her end. I offered to stop our session so she could seek shelter. She told me she would not have time to find shelter and wanted to continue our meeting. And so, we continued... But soon, Odessa’s sirens broke the silence, and it was my turn to decide what to do; should I continue our session or try to find a bomb shelter for myself? I decided to stay because I thought that was the right thing to do morally, professionally, and personally.I eventually left Odessa, but only after a bomb destroyed a house next to mine, and I saw a family, my neighbors, perish in the destruction. I am now a member of one of Slovakia’s Non-Governmental Organizations (NGOs) and work in a mobile brigade providing medical and psychological support to refugees. I can remember every one of my clients. Children, adults... I can remember their stories, their traumas, their memories of the horrors of war and devastation. Sometimes I meet with them only once, and they move on to another refugee center or are on their way to a Western part of Ukraine, trying to escape the war. And frequently, I do not know how many sessions I will be able to have with clients. Sometimes it is only one time, and sometimes we can meet for many months. Initially, I thought, What can I do in one therapy session? Now, I know that I can do a lot. I can provide people who survived the most inhuman conditions and witnessed death and destruction around them with a space and time to talk through and process their experiences. I am their support, and they lean on me as they try to make sense of what has happened to them and their country. I always tell my clients that my goal as a psychotherapist is to help them withstand, survive, and hold on while still being able to continue to function in a country at war. All I can do is treat each of the therapy sessions as our last one and try to provide as many strategies and skills as possible to cope with anxiety and depression, to be able to function, and to live in the present.Every session is about installing hope, moving slowly forward, and away from traumatic events. One of my clients, a 14-year-old boy, was diagnosed with a neurological condition, involuntary facial muscle spasm, or tics. He was barely talking when I first saw him, and I decided to use art therapy as a trauma-processing tool during one of the therapy sessions. He was drawing an explosion, fire, and destruction of his neighbor’s house. He blacked out the horrors of his experience to preserve his strength. Yet, he began slowly remembering his experiences, re-creating the story of his trauma, and making memories. I was fortunate to work with [End Page E4] him for many months, carefully and thoughtfully helping him re-create the sorry of his trauma, helping to become its witness. Ultimately, it was great to see that he could control his memories and his emotional stress; he felt empowered and in control.Eva RegelThis is the story of Irina Deyneka, one of many Ukrainian psychotherapists working in Ukraine, providing mental health support to a nation ravaged by...

We critically reconsider an old hypothesis of the role of the dekad in Pythagorean philosophy. Unlike Zhmud, we claim that: 1) the dekad did play a role in Philolaus’ astronomical system, and 2) Aristotle did not project Plato’s theory of the ten eidetic numbers onto the Pythagoreans. We claim that the dekad, as the τέλειος ἀριθμός, should be understood in Philolaus’ philosophy as completeness and the basis of counting in Greek – as in most other languages – in a decimal (...) system. Additionally, we argue that the number ten is not even a candidate for the τέλειος ἀριθμός in Plato’s philosophy. As a final result of our discussion, we compare and contrast Philolaus’, Plato’s, and Speusippus’ accounts of completeness in relation to numbers. (shrink)

As a cognitivist about emotions, Socrates takes the fear of death to be a belief that death is a bad thing for the one who dies. Socrates, however, thinks there are reasons for thinking death is not a bad thing at all, and might even be a blessing. So the question considered in this paper is: how would Socrates explain the fact that so many people believe death is bad?

The offer-and-acceptance analysis has long been questioned as not (easily) applicable to certain methods of contracting. This paper looks at this analysis through the prism of normative powers and identifies much deeper problems with the analytic explanation of how such unilateral normative powers as offer and acceptance can generate such a normative result as concluding a contract. It argues that even if the powers to offer and accept are exercised, as they are in certain methods of contracting, these are not (...) the normative powers that create contractual obligations; such obligations are always created by the jointly exercised power to contract. The paper substantiates an account of the power to contract as a sui generis normative power and explains the role the unilateral powers to offer and to accept play when they are exercised, while also explaining why there is no need to ‘invent’ offering and accepting where there are none.

The word excellence is derived from the Latin word excellentia, and it means the quality of being extremely good. Human excellences could be defined as those human qualities that make a person outstanding, exceptional, superior, or, in one word, the best of one's kind in any field of human activities. Frequently, it is synonymously used with the word virtue, narrowly meaning moral excellence.

In her seminal attack on modern moral philosophy, G. E. M. Anscombe claims that Kant's ‘rule about universalizable maxims is useless without stipulations as to what shall count as a relevant description of an action with a view to constructing a maxim about it’. Although this so-called problem of relevant descriptions has received considerable attention in the literature, there is little agreement on how it should be understood or solved. My aim in this paper is, first, to clarify the problem (...) by clearing up several misunderstandings, and, second, to show that the problem is rooted in a standard assumption about Kant's stance on the scope of moral principles—an assumption that precludes its solution. I argue that the problem consists in the fact that Kant's formula of universal law seems to stand in need of an account of moral sensibility that does not render the formula superfluous. But, as my discussion of existing solutions reveals, there can be no such account. Instead, I propose a dissolution: we should think of the formula of universal law itself as Kant's account of moral sensibility. In order to do so, we must reject the standard assumption that a principle is universal if and only if it holds for all instances of the action type that it specifies. (shrink)

Based on a dual process view of ethical judgment, we examine the role of empathic concern and perspective taking on the acceptability of lying to protect the company. We hypothesize that these traits will matter to a different extent under conditions of high and low perceived time hurriedness. Our research hypotheses are tested in a survey of 134 US workers. Results show that empathic concern reduces the acceptability of lying to protect the company for individuals who tend to do things (...) quickly and feel in a hurry at work. On the other hand, perspective taking reduces the acceptability of lying for individuals who experience low levels of time hurriedness. Theoretical and practical implications of the findings are discussed. (shrink)

En el Gran Discurso de Protágoras, en el diálogo platónico que lleva su nombre, Platón pone en boca de Protágoras un mito acerca del origen, desarrollo y naturaleza del ser humano, que es de gran relevancia filosófica. Se expresa que los dioses crearon a los seres mortales desde dos elementos: la tierra y el fuego. A su vez, también asignaron dos titanes, Epimeteo y Prometeo, para que proveyeran a los mortales de sus facultades. ¿Acaso esto implica que la creación no (...) fue terminada por los dioses? ¿Hasta qué punto los dioses crearon enteramente al ser humano? ¿Podría afirmarse que este es un mito creacionista? El desarrollo de los seres vivientes puede dividirse en cuatro instancias. A lo largo de este artículo, se proponen distintos modelos hermenéuticos para responder los interrogantes mencionados anteriormente. (shrink)

We suggest that understanding unethical behavior in organizations involves understanding how people view themselves and their relationships with others, a concept known as self-construal. Across multiple studies, employing both field and laboratory settings, we examine the impact of three dimensions of self-construal (independent, relational, and collective) on unethical behavior. Our results show that higher levels of relational self-construal relate negatively to unethical behavior. We also find that differences in levels of relational self for men and women mediate gender differences in (...) unethical behavior. We discuss both the theoretical and practical implications of these findings. (shrink)

As in science and philosophy, thought experiments in mathematics link a problem to new epistemic resources that are unavailable in a given practice, e.g., Euclidean geometry. Thought experiments invite us to perform an imaginary scenario involving counterfactual, deductive and sensory elements. This chapter aims to pinpoint the beneficial peculiarities of thought experiments in mathematics in comparison with inferences, diagrams and calculative procedures. Reflection about thought experiments assists us to realize both the limits and opportunities in mathematical thinking. Henceforth, the analysis (...) of examples suggests a broader understanding of mathematical, thought and experiment. (shrink)

The debates between various Buddhist and Hindu philosophical systems about the existence, definition and nature of self, occupy a central place in the history of Indian philosophy and religion.

The aim of this article is to discuss quantitative content analysis as established in communication sciences as a method for research in business ethics. We argue that communication sciences and business ethics are neighboring disciplines, which allow the transfer of quantitative content analysis from communication sciences to business ethics. Technically, quantitative content analysis can be applied through human as well as software coding. Examples for both applications are provided and discussed. We make reference to the software solutions ‘Leximancer’, ‘Crawdad’, and (...) ‘Wordle’, and examine their suitability and limitations with regard to ethical questions for researching business ethics. We recommend a mixed‐method approach, combining human and software coding. Furthermore, we propose a three‐step process that discusses quantitative content analysis as a method for business ethics, including an ethical research objective, and most importantly, concluding with ethical reasoning and interpretation of the quantitative results.

Invertebrate animals are frequently lumped into a single category and denied welfare protections despite their considerable cognitive, behavioral, and evolutionary diversity. Some ethical and policy inroads have been made for cephalopod molluscs and crustaceans, but the vast majority of arthropods, including the insects, remain excluded from moral consideration. We argue that this exclusion is unwarranted given the existing evidence. Anachronistic readings of evolution, which view invertebrates as lower in the scala naturae, continue to influence public policy and common morality. The (...) assumption that small brains are unlikely to support cognition or sentience likewise persists, despite growing evidence that arthropods have converged on cognitive functions comparable to those found in vertebrates. The exclusion of invertebrates is also motivated by cognitive-affective biases that covertly influence moral judgment, as well as a flawed balancing of scientific uncertainty against moral risk. All these factors shape moral attitudes toward basal vertebrates too, but they are particularly acute in the arthropod context. Moral consistency dictates that the same standards of evidence and risk management that justify policy protections for vertebrates also support extending moral consideration to certain invertebrates. Moving beyond a vertebrate-centered conception of welfare can also clarify foundational moral concepts in their own right. (shrink)

Many scholars consider that Socrates in the Lysis holds that friendship and love are egoistic and utility-based. In this paper, I will argue against those readings of Plato’s Lysis. I will analyze how Socrates treats utility and egoism in the many different kinds of friendship he discusses in the dialogue, from parental love, like-to-like, and unlike-to-unlike relationships, to the accounts of friendship rooted in the human relation to the good and the ways in which we can belong with some other (...) human beings. The upshot of my paper is twofold. I endeavor to prove that some of these relationships, as Plato’s Socrates discusses them, are not egoistic and that Plato represents and valorizes a particular type of friendship having to do with philosophy and philosophical way of life, which is for the sake of another.

The aim of this paper is to elucidate the origin, development and nature of human beings as it is described in Plato’s Protagoras myth. My main claim is that, according to this story, the human is a multi-dimensional being with various aspects and dispositions. After the creation of mortals had been finished, the human dispositions were further developed and differentiated through time. The creation and further development of living beings is to be divided into four stages, out of which the (...) pre-political and political are of particular significance for humans. I will attempt to show that each of these stages can be better accounted for by using the different hermeneutical models, or by finding out which theory underlines each of them. (shrink)

In Protagoras’ so called Great Speach, in Plato’s dialogue named after him, the Greek philosopher attributes the sophist a myth about the origin, development and nature of human beings, which has philosophical relevance. It is said that the gods created the mortal beings out of two elements, earth and fire. They assigned two titans, Epimetheus and Prometheus, to provide mortals with their faculties. Do this implies that creation had not been finished by the gods? To what extent do the gods (...) entirely create human beings? Is this mith a creationist one? In this paper, the development of living beings is divided in four stages, and different hermeneutic and explanatory models are proposed to adress the myth and answer the questions raised before.

We apply the “wisdom of the crowd” idea to human category learning, using a simple approach that combines people's categorization decisions by taking the majority decision. We first show that the aggregated crowd category learning behavior found by this method performs well, learning categories more quickly than most or all individuals for 28 previously collected datasets. We then extend the approach so that it does not require people to categorize every stimulus. We do this using a model‐based method that predicts (...) the categorization behavior people would produce for new stimuli, based on their behavior with observed stimuli, and uses the majority of these predicted decisions. We demonstrate and evaluate the model‐based approach in two case studies. In the first, we use the general recognition theory decision‐bound model of categorization (Ashby & Townsend, ) to infer each person's decision boundary for two categories of perceptual stimuli, and we use these inferences to make aggregated predictions about new stimuli. In the second, we use the generalized context model exemplar model of categorization (Nosofsky, ) to infer each person's selective attention for face stimuli, and we use these inferences to make aggregated predictions about withheld stimuli. In both case studies, we show that our method successfully predicts the category of unobserved stimuli, and we emphasize that the aggregated crowd decisions arise from psychologically interpretable processes and parameters. We conclude by discussing extensions and potential real‐world applications of the approach. (shrink)

The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation. This failure is usually interpreted as a difficulty in assigning two separate episodic tokens to the same visual type. Thus, RB can provide useful information about which representations are (...) treated as the same by the visual system. Two experiments tested whether RB occurs for repeated objects that were either in identical orientations, or differed by 30, 60, 90, or 180°. Significant RB was found for all orientation differences, consistent with the existence of orientation-invariant object representations. However, under some circumstances, RB was reduced or even eliminated when the repeated object was rotated by 180°, suggesting easier individuation of the repeated objects in this case. A third experiment confirmed that the upside-down orientation is processed more easily than other rotated orientations. The results indicate that, although object identity can be determined independently of orientation, orientation plays an important role in establishing distinct episodic representations of a repeated object, thus enabling one to report them as separate events.

In this paper I will discuss Aristotle?s controversial philosophical views on women. I will critically examine three main interpretations of his claim that women have deliberative faculty?without authority?. According to the first line of interpretation, Aristotle has in mind that women?s incapacity of advice-giving and decision-making in public affairs are determined by conventions in the political context of his time. I will attempt to point out the disadvantages of this kind of interpretation. Furthermore, I will put forward the reasons why (...) is implausible the more recent interpretation, given by Marguerite Deslauriers. According to her reading, the lack of authority of deliberative faculty in women means nothing else than the tasks over which women have authority are for the purpose of the tasks put forth by men. The prevailing interpretation among scholars is that, in Aristotle?s view, women are naturally inferior to men, due to the fact that they are all too frequently overruled by the irrational?forces? of their nature. I will argue that this line of interpretation elucidates what Aristotle presumably has in mind, although it makes his account of women and their rationality, if not inconclusive, then indisputably problematic. In other words, I attempt to prove that, if the prevailing line of interpretation is correct, such view of women produces some philosophically?insurmountable? problems for Aristotle. The aim of the last section of the paper is to point out how some of these problems could eventually be resolved. (shrink)

This paper investigates the role of pictures in mathematics in the particular case of Cayley graphs—the graphic representations of groups. I shall argue that their principal function in that theory—to provide insight into the abstract structure of groups—is performed employing their visual aspect. I suggest that the application of a visual graph theory in the purely non-visual theory of groups resulted in a new effective approach in which pictures have an essential role. Cayley graphs were initially developed as exact mathematical (...) constructions. Therefore, they are legitimate components of the theory (combinatorial and geometric group theory) and the pictures of Cayley graphs are a part of practical mathematical procedures. (shrink)

Parallels between cancer and ecological systems have been increasingly recognized and extensively reviewed. However, a more unified framework of understanding cancer as an evolving dynamical system that undergoes a sequence of interconnected changes over time, from a dormant microtumor to disseminated metastatic disease, still needs to be developed. Here, we focus on several examples of such mechanisms, namely, how in cancer niche construction a metabolic adaptation and consequent change to the tumor microenvironment becomes an important factor in evasion of the (...) predator, facilitating disease progression; how tumor establishment and propagation is driven by the tumor’s own keystone species, the cancer stem cells; and how the succession of stages of metastatic dissemination can be informed by ergodic theory and forest ecology.

A widespread assumption in experimental comparative cognition is that, barring compelling evidence to the contrary, the default hypothesis should postulate the simplest cognitive ontology consistent with the animal’s behavior. I call this assumption the principle of cognitive simplicity . In this essay, I show that PoCS is pervasive but unjustified: a blanket preference for the simplest cognitive ontology is not justified by any of the available arguments. Moreover, without a clear sense of how cognitive ontologies are to be carved up (...) at the joints—and which tools are appropriate for the job—PoCS rests on shaky conceptual ground. (shrink)

Self-generation of knowledge can activate deeper cognitive processing and improve long-term retention compared to the passive reception of information. It plays a distinctive role within the concept of inquiry-based learning, which is an activity-oriented, student-centered collaborative learning approach in which students become actively involved in knowledge construction. This approach allows students to not only acquire content knowledge, but also an understanding of investigative procedures/inquiry skills – in particular the control-of-variables strategy (CVS). From the perspective of cognitive load theory, generating answers (...) and solutions during inquiry-based learning is inefficient as it imposes an intrinsic and extraneous load on learners. Previous research on self-generation of content knowledge in inquiry-based learning has demonstrated that (1) a high cognitive load impairs retention of the generated information, (2) feedback is a fundamental requirement for self-generation of complex content knowledge, (3) self-generation success is key to long-term retention and (4) generating and rereading place different demands on learners. However, there is still no research on the self-generation of scientific reasoning skills and the interaction between the retention of these skills with prior knowledge, feedback and self-generation success. That is why this experiment was conducted. The focus of this research is to analyze the distinctive role of self-generation of scientific reasoning skills within the concept of inquiry-based learning and to identify the influence of prior knowledge and self-generation success on short-term and long-term retention. For this purpose, an experiment involving 133 6th and 7th graders was conducted. An inquiry activity that included the self-generation of scientific reasoning skills was compared to an inquiry task that had students simply read information about the experimental design. We used both an immediate and a delayed test to examine which treatment better developed a deeper understanding of CVS and an ability to apply this knowledge to novel problems (transfer). Direct instruction was clearly superior to self-generation in facilitating students’ acquisition of CVS immediately after the inquiry task. However, after a period of one week had elapsed, both treatment conditions turned out to be equally effective. A generation effect was only found among students with high self-generation success after a 1-week delay. (shrink)

White matter makes up about fifty percent of the human brain. Maturation of white matter accompanies biological development and undergoes the most dramatic changes during childhood and adolescence. Despite the advances in neuroimaging techniques, controversy concerning spatial, and temporal patterns of myelination, as well as the degree to which the microstructural characteristics of white matter can vary in a healthy brain as a function of age, gender and cognitive abilities still exists. In a selective review we describe methods of assessing (...) myelination and evaluate effects of age and gender in nine major fiber tracts, highlighting their role in higher-order cognitive functions. Our findings suggests that myelination indices vary by age, fiber tract, and hemisphere. Effects of gender were also identified, although some attribute differences to methodological factors or social and learning opportunities. Findings point to further directions of research that will improve our understanding of the complex myelination-behavior relation across development that may have implications for educational and clinical practice.

The question "Where do we come from?" has fascinated philosophers, scientists, and artists for generations. This book reorients the question of the matrix as a place where everything comes from (_chora_, womb, incubator) by recasting it in terms of acts of "matrixial/maternal hospitality" producing space and matter of and for the other. Irina Aristarkhova theorizes such hospitality with the potential to go beyond tolerance in understanding self/other relations. Building on and critically evaluating a wide range of historical and contemporary (...) scholarship, she applies this theoretical framework to the science, technology, and art of ectogenesis (artificial womb, neonatal incubators, and other types of generation outside of the maternal body) and proves the question "Can the machine nurse?" is critical when approaching and understanding the functional capacities and failures of incubating technologies, such as artificial placenta. Aristarkhova concludes with the science and art of male pregnancy, positioning the condition as a question of the hospitable man and newly defined fatherhood and its challenge to the conception of masculinity as unable to welcome the other.

Like Socrates, Aspasia did not leave any writings. We know about her from secondary sources. In this paper, I will show a number of things in the reports of what Aspasia said and did that are philosophically interesting, especially in what they show about dealing with various kinds of crises, from marital to political ones. First, I will argue for the most probable reconstruction of her life. Second, I will elucidate what kind of method Aspasia employed when considering marital issues. (...) Third, I will endeavor to prove that Plato’s representation of Aspasia was not a mockery, as some authors argue. Furthermore, the most significant philosophical points of Aspasia’s Funeral Speech will be highlighted and assessed. Eventually, I will attempt to figure out what Plato’s reasons might have been to ascribe this speech to a woman. (shrink)

I analyse some of the key evolutionary issues that arise in the study of consciousness from a bio-philosophical point of view.

Behavioural flexibility is often treated as the gold standard of evidence for more sophisticated or complex forms of animal cognition, such as planning, metacognition and mindreading. However, the evidential link between behavioural flexibility and complex cognition has not been explicitly or systematically defended. Such a defence is particularly pressing because observed flexible behaviours can frequently be explained by putatively simpler cognitive mechanisms. This leaves complex cognition hypotheses open to ‘deflationary’ challenges that are accorded greater evidential weight precisely because they offer (...) putatively simpler explanations of equal explanatory power. This paper challenges the blanket preference for simpler explanations, and shows that once this preference is dispensed with, and the full spectrum of evidence—including evolutionary, ecological and phylogenetic data—is accorded its proper weight, an argument in support of the prevailing assumption that behavioural flexibility can serve as evidence for complex cognitive mechanisms may begin to take shape. An adaptive model of cognitive-behavioural evolution is proposed, according to which the existence of convergent trait–environment clusters in phylogenetically disparate lineages may serve as evidence for the same trait–environment clusters in other lineages. This, in turn, could permit inferences of cognitive complexity in cases of experimental underdetermination, thereby placing the common view that behavioural flexibility can serve as evidence for complex cognition on firmer grounds.

This article challenges the orthodox explanation of the normative connection between contracting parties: The promisee is regarded as having a superior position vis‐à‐vis the promisor, a position manifesting itself in the promisee's authority or control over the promisor's performance, and supported, in particular, by the promisee's supposed power, or at least some sort of ability falling short of a normative power, to “waive” the promisor's duty of performance. The article demonstrates that this explanation is rooted in a one‐sided, and ultimately (...) wrong, understanding of correlativity in contractual relations and suggests a better understanding, one truly capable of accounting for contractual bilaterality.

In guarding against inferential mistakes, experimental comparative cognition errs on the side of underattributing sophisticated cognition to animals, or what I refer to as the underattribution bias. I propose eliminating this bias by altering the method of choosing the default, or null, hypothesis. Rather than choosing the most parsimonious null hypothesis, as is current practice, I argue for choosing the best-evidenced hypothesis. Doing so at once preserves the risk-controlling structure of the current statistical paradigm and introduces a sensitivity to probability-conferring (...) empirical and theoretical information. This analysis illustrates how values like parsimony can covertly shape statistical-experimental design and inference. (shrink)

The article is devoted to spelling errors of Russian learners in a French-speaking environment. Based on 1,816 spelling errors, the analysis focuses on four mechanisms (transposition, insertion, omission, and substitution), and the influence of contextual and non-contextual (cognitive, inter- and intralinguistic, extralinguistic) factors is taken into account for each mechanism in question. Despite the multidimensional nature of the factors involved, the recurrence of certain errors makes it possible to distinguish clear trends in the acquisition of linguistic facts. In addition, a (...) quantitative analysis of the obtained data allows cross-sectional studies of errors, which traces back the steps in the acquisition of various aspects of Russian spelling, from A1 to C1 level for the first time. Moreover, the qualitative analysis of errors provides valuable data for pedagogical materials. (shrink)
